Merging Cells in SAS

If you look immediately underneath the example you cited, the paper author provides the program name that he used to create the output. Perhaps if you contacted the paper author, you could obtain his macro program that performed the cell merge using RTF control strings.

I have done a similar report using just PROC REPORT, by making a character variable, for example, with the N and PCTN concatenated into 1 string: NNN (yy.y%) and then using the character string with PROC REPORT instead of the 2 separate variables.

My paper "Creating Complex Reports" has 3 examples of creating such a demographic report and can be downloaded from here:
